Final answer:
The filmmakers compared Lewis and Clark to the expedition of Meriwether Lewis and Lieutenant William Clark, which was funded by President Jefferson in 1803.
Step-by-step explanation:
The filmmakers compared Lewis and Clark to the expedition of Meriwether Lewis and Lieutenant William Clark. The Lewis and Clark expedition was funded by President Jefferson in 1803 with a mission to explore the newly acquired Louisiana Purchase and find potential trade routes to the Pacific. The expedition lasted from 1804 to 1806 and brought back valuable information about the geography, native tribes, and flora and fauna of the areas they explored.
Thus, this expedition, which was commissioned by President Thomas Jefferson in the early 19th century, aimed to explore the western territories of the United States. The filmmakers likely drew parallels to highlight similarities or contrasts between the two exploration narratives.
